HANDLING AND CARE OF TREATED MATERLALS 



No treated piling, lumber or timber will be accepted that has been injured during 

 treatment In- rubbing or scraping against tram arms or ri^•et heads, or by rough 

 handling. 



In handling treated material extreme care must be used not to damage the 

 edges of lumber and timbers, or to break through the portions penetrated by the 

 preservative and thus expose untreated wood. Sharp pointed tools, such as cant 

 hooks, peavies, pickaroons and crowbars, must not be used except in the ends of 

 treated sawed material and in the ends, or within three (3) feet from the ends, of 

 creosoted piling. 



In the rafting of creosoted piling, the use of dogs will only be permitted, provided 

 the dogs are driven within three (3) feet of either end of the pile. Should the creosoting 

 company place these dogs farther from the ends than above specified, the piling may 

 be rejected. All dog holes must be plugged with creosoted plugs. 



No treated material carried in stock by the creosoting company can be applied on 

 the purchaser's contract without the consent of the purchaser. If agreeable to the 

 purchaser to apply stock materials on his contract, such material nmst stand the same 

 rigid inspection as hereinbefore specified for the various classes of material.
